    The cover picture shows the X-ray crystal structures of thecompounds obtained by the alkylation of a conjugated por-phyrinogen precursor at its macrocyclic nitrogen atoms with2-(methylenenaphthyl) groups. The presence of the N-alkylgroups introduces intermolecular stacking interactionswhich culminate in a 1-dimensional stacked array for thefully N-substituted derivative. The N-alkylation enhances theability of the compounds to form anion radical and cationradical species and permits tuning of the electrochemicalproperties of the core porphyrinogen. Details are discussedin the article by J. P. Hill et al. on p. 2893ff.
